However, what's wrong with the Sonitus?
 
 

Be careful with Micro, or any other filter that isn't completely transparent. Transparency is what you want in a HPF. You don't want to be able to hear it.

I just had an idea (gosh i'm a frikkin geenyous)
 
Mixers have low cut  (hi-pass) buttons on each channel. Not like the gui needs another button but how 'bout that? - about 100hz is it?

The only problem is the ones in mixers aren't as helpful as you might want, because they're limited by being hardware - the frequency is usually fixed and the slope isn't all that steep. The Sonitus EQ or ProChannel EQ is more flexible. You could always create a template that has a Sonitus EQ set for the desired preset in every channel.

Bark of the Dog, how is that cpu. Never tried it on more than two tracks.

 
That's really good advice, not so much because it's a traditional steep highpass filter, but because the resonance options let you get more mileage out of its "highpassness." For example, you can use it selectively to get rid of most of the lows, but boost the upper lows or lower mids a bit so you have the option to "warm up" the sound while also cutting out the lowest frequencies. CPU consumption is modest.
 
While maybe not exactly what PilotGav wants, for some signals it could be a better choice.

I have a Focusrite ToneFactory back in the UK. That was my first intro to haveing both a sweepable high pass (up to 320 I think) and a resonant bump (switch in and out rather than continuous). That really opened up the bass end when all I had was Spirit folio mixers. 
 
There's a feature request for a low and high pass option somewhere in the history. All the time the Pro channel eq is fixed in the chain, I can't see there being a need for it. High and low pass on sends however I think would be welcome (there's another feature request for this too). To help sculp sounds going into reverbs and parallel set ups.

Sonitus! Jeeze! Lol
 
Thanks :-)

I love the idea of ProChannel and have used it exclusively in the past... however I just find that I have a mental block somehow due to the interface/workflow. One example of many is that if I expand the EQ, it covers up the MSR buttons. I know this seems small, but its just little interface quirks like this which have turned me off it.
 
It's a shame because in concept it really is awesome. I just think it needs a huge interface/workflow overhaul.

On that one aspect I agree with you and I believe there's already a Feature Request to have the MSR buttons visible on the fly-out.

You can dock the ProChannel on the other side of the track view.

Check out Week 57 in Friday's Tip of the Week. Don't be put off by the title, I'm pretty sure it will do what you want and then some.

Off topic, but thanks for bringing that tip to my attention - it just helped to save a vocal track that was fine except for a couple of plosives in one verse and wouldn't have been easy to rerecord!
